Solid-solid phase change materials have been synthesized via radical polymerization of acrylate monomers bearing linear alkyl side chains as the phase changing motifs and epoxy rings as crosslinkable moieties.Thermal treatment of the resulting copolymers produced form-stable solid-solid phase change materials (S-S PCMs) with thermal storage capacities ranging from 95 J/g to 125 J/g and thermal transitions occurring between 30 <sup>0</sup>C and 55 <sup>0</sup>C. Copolymers with various compositions have been synthesized to optimize the thermal and optical properties of the S-S PCMs materials. The structure-property relationships have been established using NMR spectroscopy,X-ray Diffraction,, Differential Scanning calorimetry, Thermal Gravimetric Analysis , UV-Vis Spectroscopy, Near Infra-Red spectroscopy and Scanning Electron Microscopy. The change in melt-inducedchange in transmittance contrast makes these materials promising candidates for “smart” building enclosures capable of passive thermal regulation.
